Problems solved by technology

However, the blood vessels around the heart are intricate, and medical staff will inevitably encounter a situation where a main blood vessel is divided into two or three branches, thus requiring two or more medical staff to hold a clamper to clamp one of the blood vessels
Due to too many operators, this will cause the medical staff to collide with each other when clamping blood vessels, causing secondary damage to blood vessels

Embodiment 1

[0064] see Figure 1-4 , a blood vessel holder for thoracic and cardiovascular surgery, comprising a handle 10, a clamping rod 20, and a clamping head 30,

[0065] The handle 10 is used to provide a part of the hand-held blood vessel holder;

[0066] The clamping rod 20 is fixedly connected to the left end of the handle 10. The clamping rod 20 is made of a metal corrugated hose, and the clamping direction of the clamping head 30 is adjusted according to the random bending of the clamping rod 20;

[0067] The clamping head 30 is fixedly connected to the left end of the clamping rod 20, and is used for clamping the main blood vessel and the branch vessels of the main blood vessel;

[0068] The clamping head 30 includes a fixed head 31, a clamping head one 32, a fixed rod 33, a turning head 34, a clamping head two 35, a clamping head three 36, and a handle 37;

[0069] The fixed head 31 is fixedly connected to the left end of the clamping rod 20, and is used for the positioning...

Embodiment 2

[0086] see Figure 5-8 , in order to realize the simultaneous clamping of the main blood vessel or the main blood vessel and the branch blood vessels, the clamping head 1 32, the clamping head 2 35, and the clamping head 3 36 are designed. Through the cooperation of the three clamping heads, the main blood vessel and the branching Simultaneous clamping of branch vessels.

[0087] The clamping head 1 32 , clamping head 2 35 , and clamping head 3 36 are evenly distributed on the outer wall of the fixing head 31 with the round point of the fixing head 31 as the center point.

[0088] Described clamp chuck one 32, clamp clamp two 35, clamp clamp three 36 all comprise fixed plate 332, support frame 321, air bag 322, inflation and deflation mechanism 323, slide bar one 324, L-shaped strut one 325, Connecting rod one 326, clamp block one 327, slide bar two 328, L-shaped strut two 329, connecting rod two 330, clamp block two 331;

[0089] The fixed plate 332 is respectively fixedly ...

Abstract

The invention discloses a vascular clamp for cardiovascular thoracic surgery. The vascular clamp comprises a clamping head for clamping a main blood vessel and branch blood vessels of the main blood vessel; wherein the clamping head comprises a fixing head fixedly connected to the left end of a clamping rod, a forceps clamping head I fixedly connected to the outer wall of the fixing head, a fixing rod fixedly connected to the right end of the forceps clamping head I and located on the upper surface of the fixing head, a steering head, a forceps clamping head II rotationally connected to the outer wall of the fixing head, a forceps clamping head III rotationally connected to the outer wall of the fixing head, and turning handles respectively fixedly connected to the forceps clamping head II and the forceps clamping head III. By means of the vascular clamp, when a medical worker conducts a blood vessel suture operation, the main blood vessel and the branch blood vessels can be clamped at the same time, without simultaneous operation of multiple persons, which avoids the situation that when the medical worker clamps the branch blood vessel, the vascular clamps collide with one another to cause secondary damage to the blood vessels.

Description

technical field [0001] The invention relates to the technical field of blood vessel clamping, in particular to a blood vessel clamper for thoracic and cardiovascular surgery. Background technique [0002] Cardiothoracic surgery includes the treatment of diseases in cardiac surgery and general thoracic surgery. Among them, cardiac surgery is a relatively young discipline in the branch of surgery, which treats heart disease with surgery. It mainly studies the diagnosis and treatment of cardiovascular trauma, pericardial disease, congenital heart disease, and cardiac tumors. [0003] The heart is the driving force of the human circulatory system. The human heart is basically the same size as a person's fist. It is located on the diaphragm, between the mediastinum, the middle of the chest cavity to the lower left, and the space between the two lungs to the left. The main function of the heart is to promote blood flow, provide sufficient blood flow to the organs and tissues of ...
